Aircraft Life Cycle and Development

Question 1

leisure traveler

Answer 1

price sensitive, check in 3 hrs before, baggage, in-flight entertainment, comfort less important

Question 2

business traveler

Answer 2

flexibility > ticket price, quick check in, lot of hand baggage, in-flight communication, comfort and service top priority

six traveler tribes of the future

Answer 3

simplicity searchers, cultural purists, social capital seekers, reward hunters, obligation meeters, ethical travelers

Question 4

simplicity searchers

Answer 4

ease, transparency, outsourcing decision making

Question 5

cultural purists

Answer 5

unfamiliar culture, new way of living

Question 6

social capital seekers

Answer 6

max social reward, exploit potential of digital media

Question 7

reward hunters

Answer 7

busy lives, seek ROI, indulgent experiences

Question 8

obligation meeters

Answer 8

business, need to be in place and time without fail

Question 9

ethical travelers

Answer 9

environmentally concerned, high awareness on local economy

Question 10

green responsibilities

Answer 10

eco-ethical concerns will be a feature of the future consumer landscape

Question 11

work-life compounds

Answer 11

broad casualization of business practices and arrangements

Question 12

option shock

Answer 12

leads to bundles

Question 13

enterprise networking

Answer 13

online networking more important now than ever before

Question 14

peer power

Answer 14

social media boosted brand loyalty

Question 15

narrative data

Answer 15

big data personalizing services

Question 16

pricing gets personal

Answer 16

perfect price discrimination - new tourist groups

Question 17

Aircraft life cycle

Answer 17

genesis, design, development, production, modifications, product support, disposal

Question 18

airplane development process

Answer 18

research, specification, conceptual design, preliminary design, detail design, flight test, operations, growth versions

Question 19

aircraft design

Answer 19

requirements, conceptual design, preliminary design, detail design, fabrication

Question 20

enabling technologies for airplane concept

Answer 20

aerodynamics, propulsion, flight and load control, airborne systems, structural concepts, materials/manufacturing

Question 21

aircraft commonality

Answer 21

airline typically wants same propulsion system, flight deck, components, and sub systems, does not affect direct operating costs

Question 22

v-model requirements engineering

Answer 22

consumer requirements - component level design requirements - critical design review - components - assemblies - system - end product

Question 23

validation

Answer 23

process of confirming that requirements for a specific intended use have been fulfilled

Question 24

verification

Answer 24

iterative process during design stage to make sure requirements are fulfilled

Question 25

aircraft conceptual design

Answer 25

mission analysis, initial sizing (overall weight), parametric sizing (optimal engine thrust and wing area), constraint diagram, configuration options, weight estimation

Question 26

costs

Answer 26

marketing, systems engineering, design, production, operations

Question 27

economic end of life

Answer 27

operating cost exceeds revenue capacity, availability of significantly more efficient aircraft, environmental regulations make operations less acceptable

Question 28

structural end of life

Answer 28

repair of the structure is no longer economically feasible, overall fatigue life usually twice as long as the minimum designed service life

Question 29

aircraft residual value

Answer 29

age, operational history, production cycle, manufacturer status, market condition, environmental regulations

Question 30

cost estimation relation(CER)

Answer 30

costs = a*(P^x)
a - system specific constant, P - independent const driving parameter, x - system specific sensitivity factor

Question 31

degression factors

Answer 31

factor of the technological state of the art, technical quality factor, experience related factor, learning factor in production

Question 32

man-year

Answer 32

enables cost estimations independent of time related influences, inflation, different companies, different countries, different currencies, exchange rate fluctuations

Question 33

development costs

Answer 33

unrealistic (used to sell concept), minimum credible (used to win a call for tenders), ideal or theoretical (assuming everything goes to plan), realistic (including some uncertainty), effective costs until end of development (overall costs after development)

Question 34

production costs

Answer 34

in increasing order, materials, manufacturing, direct services and support, technical assistance and support
